Composition of major oxide in bulk sediments from lake Baikal: ICP-AES data from P-rich samples

Fagel, Natalie | Alleman, Laurent | Granina, L | Hatert, F | Thamo-Boszo, Edit | Cloots, R | André, Luc

2006

The sediment cores were sampled with a resolution of 10 cm, resulting in a total of 290 samples (Table 2). Around 250 mg of dried sediments was mechanically crushed through 100–200-μm mesh then processed by an alkaline digestion (Lithium meta-borate) in a Pt crucible at 1000 °C for 1 h. The...

Selected electron-microprobe analyses of vivianite and santabarbaraite from Lake Baikal

Fagel, Natalie | Alleman, Laurent | Granina, L | Hatert, F | Thamo-Boszo, Edit | Cloots, R | André, Luc

2006

Electron-microprobe analyses (Table 5) were completed on a selection of grains from 11 samples, with a CAMECA SX-50 instrument (University of Louvain-la-Neuve, Belgium), under an accelerating voltage of 15 kV and a probe current of 20 nA. The standards used were the Kabira graftonite (Fe, Mn,...

SAFOD Main Hole downhole logging data phase 1.2 1744-1932m

SAFOD

2008

SAFOD is motivated by the need to answer fundamental questions about the physical and chemical processes controlling faulting and earthquake generation within a major plate-bounding fault. SAFOD will drill and instrument an inclined borehole across the San Andreas Fault Zone to a depth of 3.2...

SAFOD

2007

SAFOD is motivated by the need to answer fundamental questions about the physical and chemical processes controlling faulting and earthquake generation within a major plate-bounding fault. SAFOD will drill and instrument an inclined borehole across the San Andreas Fault Zone to a depth of 3.2...

High temperature measurements of magnetic susceptibility in clay-rich layers for VER98-1-14

Demory, Francois | Oberhänsli, Hedi | Nowaczyk, Norbert | Gottschalk, Matthias | Wirth, Richard | Naumann, Rudolf

2006

High temperature measurements of magnetic susceptibility in clay-rich layers. Magnetite, characterised by a Curie temperature of 590 °C, dominates the signal.

High temperature measurements of magnetic susceptibility in diatomaceous layers for VER98-1-1

Demory, Francois | Oberhänsli, Hedi | Nowaczyk, Norbert | Gottschalk, Matthias | Wirth, Richard | Naumann, Rudolf

2006

High temperature measurements of magnetic susceptibility in diatomaceous layers. Most of the weak susceptibility is still present up to the temperature of 670 °C and carried by hematite.

Down-core variations of normalised relative paleointensity after removal of intervals affected by diagenesis

Demory, Francois | Nowaczyk, Norbert | Witt, Annette | Oberhänsli, Hedi

2006

Down-core variations of normalised relative paleointensity after removal of intervals affected by diagenesis (magnetite dissolution and/or greigite formation) and correlation to the relative paleointensity record from ODP Site 984 (Channell, 1999). In addition to AMS 14C dating and the...

Depth versus age based on relative magnetic paleointensity correlations for all six investigated sites

Demory, Francois | Nowaczyk, Norbert | Witt, Annette | Oberhänsli, Hedi

2006

In order to characterise Lake Baikal sedimentary responses to global climatic changes that may be recorded in marine sediments, we compared our paleomagnetically dated climate-proxy record from Lake Baikal with benthic and plankontic δ18O curves of ODP Site 983, a site close to ODP Site 984....

Down-core variations of the inclination and declination of ChRM of all investigated cores.

Demory, Francois | Nowaczyk, Norbert | Witt, Annette | Oberhänsli, Hedi

2006

Dashed lines mark some correlation levels of the cores from Lake Baikal with the dated δ18O record from ODP 677 (Shackleton et al., 1990), see also Fig. 3. Diagenetic features such as dissolution of magnetite and mineralization of greigite are marked according to Fig. 4. Laschamp and Iceland...

Down-core variations of normalised relative paleointensity and ARM/SIRM after diagenetic correction for CON01-603-2.

Demory, Francois | Nowaczyk, Norbert | Witt, Annette | Oberhänsli, Hedi

2006

The concentration in ferromagnetic particles is much lower in the interglacial sediments than in glacial sediments. Therefore, the NRM needs to be normalised by a concentration-related parameter, such as κLF, ARM or SIRM, in order to generate relative paleointensity records free of the...
